The answer is the cyclones shouldn't be used to try and control grind. The major factors that influence the grind-size are the feed PSD, ore characteristics (both the coarse breakage (Axb/DWi/WS AG etc), and fine grinding (BWi) parameters), grinding power, grinding media, classification efficiency and throughput rate.
